Description

滑动接触构件及活塞泵·马达
技术领域
本发明涉及一种相互滑动接触的滑动接触构件、及使用了这些滑动接触构件的活塞泵·马达。
背景技术
在日本特开2005-257035号公报中公开了如下技术：利用具有优越的相对于钢铁材料的耐咬粘性的铜合金来形成与钢铁材料的构件滑动接触的滑动接触构件。多数情况下使用铅青铜作为铜合金。
然而，由于铅青铜含有对人体有害的铅，因此，谋求利用无铅的材料来形成滑动接触构件。
因此，也考虑到了通过在与钢铁材料的构件滑动接触的滑动接触构件的滑动接触面形成高硬度且低摩擦性的非晶碳膜(所谓的类金刚石膜)来提高两个构件之间的滑动性的方法。然而，在微小异物(所谓的污染)进入了钢铁材料的构件与具有非晶碳膜的构件的滑动接触面之间的情况下，存在由微小异物使非晶碳膜损伤而导致非晶碳膜自滑动接触构件剥离的问题。
发明内容
发明要解决的问题
本发明的目的在于提供一种能够提高两个构件之间的滑动性且能够抑制非晶碳膜的剥离的两个滑动接触构件及使用了这些滑动接触构件的活塞泵·马达。
用于解决问题的方案
根据本发明的一实施方式，提供一种相互滑动接触的滑动接触构件，其中一方滑动接触构件的滑动接触部由非晶碳形成，另一方滑动接触构件的滑动接触部由铜合金或铝合金形成。
以下参照附图详细地说明本发明的实施方式和优点。

图2是用于说明使一方滑动接触构件相对于另一方滑动接触构件滑动时的咬粘负荷的图。
图3是表示磷青铜与各种非晶碳之间的咬粘性的图。
图4是表示各种铜合金与含铬的氢化非晶碳等之间的咬粘性的图。
图5是表示各种铝合金与含铬的氢化非晶碳等之间的咬粘性的图。
具体实施方式
参照图1说明本发明的实施方式的斜板型的活塞泵·马达100的结构。
活塞泵·马达100通过利用来自外部的动力旋转驱动轴1使活塞5往复移动，而作为能够供给工作油(工作流体)的泵发挥功能，另外，通过利用自外部供给的工作油的压力使活塞5往复移动且旋转驱动轴1，从而作为能够输出旋转驱动力的马达发挥功能。
图1所示的活塞泵·马达100例示了搭载于建筑机械等车辆且作为用于供给工作油的泵而使用的情况。因而，以下说明活塞泵100。在该情况下，利用搭载于车辆的发动机的动力旋转驱动驱动轴1，活塞泵100向驱动器等供给工作油。
活塞泵100包括：驱动轴1，其以旋转自由的方式支承于壳体21、壳体22；以及缸体单元2，其收纳到利用壳体21、壳体22划分的收纳室23内。
驱动轴1为棒状构件，其利用发动机的动力旋转驱动。在驱动轴1安装有伴随驱动轴1的旋转而旋转的缸体单元2。
缸体组件2为有底圆筒状构件。在缸体单元2上以与驱动轴1平行的方式开口形成有多个缸孔3。缸孔3供划分容积室4的活塞5以往复移动自如的方式插入。
在活塞5的顶端以转动自如的方式连结有滑靴10。滑靴10由圆形的平板部11以及与这些平板部11一体形成的球面座12构成。各球面座12安装于各个活塞5的顶端部，滑靴10的平板部11配设为与固定于壳体21的斜板20面接触。
当利用发动机的动力对驱动轴1进行旋转驱动、且缸体单元2旋转时，各滑靴10的平板部11相对于斜板20滑动，各活塞5以与斜板20的倾斜角度相对应的行程量沿缸孔3往复移动。各容积室4的容积根据各活塞5的往复移动增加或减少。
在用于将壳体21的开口端封闭的壳体22固定有阀板6，缸体组件2的基端面滑动接触于该阀板6。在阀板6上形成有未图示的吸入口和排出口。经由吸入口向利用缸体单元2的旋转而扩大的容积室4引导工作油，经由排出口自利用缸体单元2的旋转而缩小的容积室4排出工作油。这样，在活塞泵100中，伴随缸体单元2的旋转能够连续地进行工作油的吸入和排出。
另外，在本实施方式的活塞泵100中，将斜板20固定到了壳体21，但也可以将斜板20以能够转动的方式配置在壳体21内以能够调整偏转角度。
在活塞泵100的运转过程中，缸体单元2相对于阀板6滑动。因而，为了使活塞5能够顺畅地进行往复移动，且能够进行稳定的工作油的吸入和排出，需要提高缸体单元2与阀板6之间的滑动性。因此，在本实施方式中，利用铜合金形成缸体单元2的滑动接触面，利用非晶碳(所谓的类金刚石)形成阀板6的滑动接触面。
缸体单元2为利用模具钢(SKD11)等钢铁材料形成的有底圆筒状构件。在相对于阀板6滑动接触的缸体单元2的端面上利用烧结等已知的方法设有利用磷青铜(CA502)形成的层(膜)。这样，缸体单元2的滑动接触面(滑动接触部)利用硬度比缸体单元2的母材即钢铁材料、后述的非晶碳低的磷青铜形成。磷青铜为不含铅的无铅铜合金。
阀板6为利用模具钢(SKD11)等钢铁材料形成的圆板状构件。在相对于缸体单元2滑动接触的阀板6的端面利用物理蒸镀法(PVD)、化学蒸镀法(CVD)等已知的方法设有利用非晶碳形成的层(膜)。这样，利用硬度高于阀板6的母材即钢铁材料、磷青铜等铜合金且摩擦性比阀板6的母材即钢铁材料、磷青铜等铜合金低的非晶碳来形成阀板6的滑动接触面(滑动接触部)。形成阀板6的滑动接触面的非晶碳为掺杂有铬(Cr)等金属的氢化非晶碳(a-C：H(Cr))。
图2为验证了在滑动接触面具有铜合金、氢化非晶碳的层的两个滑动接触构件之间的咬粘性的图表。该图表表示：在使一方滑动接触构件旋转，而将固定侧的滑动接触构件压靠于旋转侧的滑动接触构件的滑动接触面的一部分的情况下，两个滑动接触构件发生了咬粘时的咬粘负荷。
如图2所示，在将由铸铁材料(FCD700)形成的滑动接触构件压靠于具有铅青铜(CAC603)的滑动接触面的滑动接触构件时的咬粘负荷高于将由铸铁材料形成的滑动接触构件压靠于具有无铅的磷青铜(CAC502)的滑动接触面的滑动接触构件时的咬粘负荷。铅青铜的相对于铸铁材料的耐咬粘性优于磷青铜的相对于铸铁材料的耐咬粘性。
相对于此，在将具有掺杂了铬的氢化非晶碳(a-C：H(Cr))的滑动接触面的滑动接触构件(母材：SKD11)压靠于具有磷青铜的滑动接触面的旋转侧的滑动接触构件(母材：SKD11)的情况下，在本次实验中未发生咬粘。另外，在将具有磷青铜的滑动接触面的固定侧的滑动接触构件压靠于具有掺杂了铬的氢化非晶碳的滑动接触面的旋转侧的滑动接触构件的情况下，也未发生咬粘。
这样，通过使一方滑动接触构件的滑动接触面为掺杂了铬的氢化非晶碳，使另一方滑动接触构件的滑动接触面为磷青铜，确认了能够大幅度地提高两个滑动接触构件之间的滑动性。
另外，在使旋转侧为具有磷青铜的滑动接触面的滑动接触构件的情况下，由于与高硬度的氢化非晶碳的滑动接触面相接触的磷青铜的滑动接触面的位置因旋转而变化，因此难以咬粘。相对于此，在使旋转侧为具有氢化非晶碳的滑动接触面的滑动接触构件的情况下，由于氢化非晶碳的滑动接触面局部地在磷青铜的滑动接触面整体上持续滑动，因此，认为较上述情况容易咬粘。
基于上述的见解得知：在活塞泵100中，期望利用磷青铜来形成旋转侧的缸体单元2的滑动接触面，利用掺杂了铬的氢化非晶碳来形成固定侧的阀板6的滑动接触面。在活塞泵100中，缸体单元2与阀板6的滑动接触面之间的表面压力因排出压力的影响而在排出口侧高于吸入口侧，由于缸体单元2在以稍微倾斜的状态接触到阀板6的情况下旋转，因此，通过在阀板6侧形成高硬度的氢化非晶碳的滑动接触面，能够提高缸体单元2与阀板6之间的滑动性，进一步能够抑制两个滑动接触面之间的磨损。但是，从耐咬粘性方面考虑，还可以利用掺杂了铬的氢化非晶碳来形成缸体单元2的滑动接触面，利用磷青铜来形成阀板6的滑动接触面。
另外，如图2所示，在利用未掺杂有金属的氢化非晶碳(a-C：H)来形成旋转侧或固定侧的滑动接触构件的滑动接触面的情况下，氢化非晶碳(a-C：H)与磷青铜之间也未发生咬粘。
因而，在活塞泵100中，在缸体单元2和阀板6之中，可以利用未掺杂有金属的氢化非晶碳来形成一个构件的滑动接触面，利用磷青铜来形成另一个构件的滑动接触面。另外，代替氢化非晶碳(a-C：H)，还可以使用不含氢的四面体非晶碳(ta-C)。如图3所示，在缸体单元2和阀板6中，利用四面体非晶碳(ta-C)来形成一个构件的滑动接触面，利用磷青铜来形成另一个构件的滑动接触面，即使在该情况下，也能够获得与掺杂了铬的氢化非晶碳(a-C：H(Cr))和磷青铜的组合等大致相同程度的咬粘性改善效果。
采用上述的本实施方式的活塞泵100能够起到以下的效果。
在活塞泵100中，由于利用磷青铜(CAC502)来形成缸体单元2的滑动接触面，利用掺杂了铬的氢化非晶碳(a-C：H(Cr))来形成阀板6的滑动接触面，因此，能够提高缸体单元2与阀板6之间的滑动性。另外，在缸体单元2以倾斜状态与阀板6滑动接触的情况下，也能够抑制缸体单元2与阀板6的两个滑动接触面之间的磨损。而且，由于磷青铜为不含铅的铜合金，因此不会对人、环境等产生不良影响。
由于缸体单元2的滑动接触面由相比于钢铁材料等金属较柔软的磷青铜(铜合金)形成，因此，在微小异物进入了阀板6与缸体单元2的滑动接触面之间的情况下，微小异物以埋入缸体单元2的磷青铜的滑动接触面的方式嵌入磷青铜的滑动接触面，而难以由微小异物导致阀板6的氢化非晶碳膜受损。由此，能够抑制阀板6的氢化非晶碳膜的剥离。
以上，说明了本发明的实施方式，但上述实施方式仅示出了本发明的应用例的一部分，其宗旨并不在于将本发明的技术范围限定于上述实施方式的具体结构。
在相互滑动接触的缸体单元2和阀板6这样的滑动接触构件中，作为形成这些滑动接触构件的滑动接触面的铜合金和非晶碳的组合，可以考虑例如表1这样的组合。
表1
如表1所示，在利用掺杂了铬等金属的氢化非晶碳(a-C：H(Cr))形成了一个滑动接触构件的滑动接触面的情况下，利用磷青铜(CAC502)、含铋(Bi)铜合金、S材、高强度黄铜(CAC303)、科森铜合金等铜合金形成另一个滑动接触构件的滑动接触面。这些铜合金为不含铅的无铅合金。另外，铜合金指的是以铜(Cu)为主要成分的合金。
如图4所示，通过利用掺杂了铬的氢化非晶碳(a-C：H(Cr))来形成一个滑动接触构件的滑动接触面，利用磷青铜、含铋铜合金、S材、高强度黄铜、科森铜合金中的任一材料来形成另一个构件的滑动接触面，相对于以往公知的铸铁材料(FCD)与磷青铜的组合或铸铁材料(FCD)与铅青铜的组合，能够改善两个滑动接触构件之间的咬粘性。另外，即使在使用了含铋铜合金、S材、高强度黄铜、科森铜合金的情况下，也能够抑制在微小异物进入时的滑动接触构件的氢化非晶碳膜的剥离。
在利用未掺杂有金属的氢化非晶碳(a-C：H)或不含氢的四面体非晶碳(ta-C)形成了一个滑动接触构件的滑动接触面的情况下，利用磷青铜(CAC502)来形成另一个滑动接触构件的滑动接触面。该情况下的咬粘性改善效果如图3所示。
而且，还可以不利用铜合金而是利用与铜合金同样地较柔软的材料即铝合金来形成一个滑动接触构件的滑动接触面。作为形成相互滑动接触的滑动接触构件的滑动接触面的铝合金与非晶碳的组合，可以考虑例如表2所示的组合。
表2
在利用掺杂有铬等金属的氢化非晶碳(a-C：H(Cr))形成了一个滑动接触构件的滑动接触面的情况下，利用铝压铸件(ADC12)、铝铸件(AC4C或NH42)、形变铝合金(A5052或A6061)等铝合金来形成另一个滑动接触构件的滑动接触面。这些铝合金为不含铅的无铅合金。另外，所谓的铝合金就是以铝(Al)为主要成分的合金。
如图5所示，通过利用掺杂了铬的氢化非晶碳(a-C：H(Cr))来形成一个滑动接触构件的滑动接触面，利用铝压铸件、铝铸件、形变铝合金中的任一材料来形成另一个构件的滑动接触面，相比于以往公知的铸铁材料(FCD)与铝铸件(AC4C)的组合、铸铁材料与铅青铜的组合(参照图4)，能够改善两个滑动接触构件之间的咬粘性。另外，即使在使用了铝压铸件、铝铸件、形变铝合金的情况下，也能够抑制在微小异物进入时的滑动接触构件的氢化非晶碳膜的剥离。
